—Routing is a challenging issue in Delay/Disruption Tolerant Networks (DTNs) due to the characteristics of high mobility of nodes and high dynamicity of network topology. The previous works did not consider the spacial information of nodes, such as dwelling time at a location when predicting the future contact of two nodes. In this paper, a novel Spacial… (More)

Delay tolerant networks (DTNs) make use of opportunistic encounters of nodes for communication. The characteristics of high mobility of nodes, frequent link variation and long communication delays in DTNs result in an absence of an instantaneous end-to-end path from any source to a destination, making routing a challenge in DTNs. To deal with this issue, a… (More)

We explore how the atomic-scale structural and chemical properties of an oxide-supported monolayer (ML) catalyst are related to catalytic behavior. This case study is for vanadium oxide deposited on a rutile α-TiO2(110) single-crystal surface by atomic layer deposition (ALD) undergoing a redox reaction cycle in the oxidative dehydrogenation (ODH) of… (More)
